sock_diag.7: Fix recvmsg() usage in the example
The msg_name field for recvmsg() call points to a caller-allocated buffer
nladdr that is used to return the source address of the (netlink) socket.
As recvmsg() does not read this buffer and fills it for a caller, do not
initialize it and instead check its value in the example.
